“一种动物要能够算，它必须知道一组物品中的每一件东西都和某一数字相对应，而最后的那个数字代表的是物品的总数。”《新科学家》说。
"But to count, an animal has to recognize that each object in a set corresponds to a single number and that the last number in a sequence represents the total number of objects," New Scientist added.
我已经减少了很多的书籍和DVD光盘，目前会当作一件物品来算，但我会尽量将总数减少到20至30之间。
Books and DVDs, which I have already reduced greatly, will be counted as one item for now, but I will try to reduce the total number to between 20 and 30.
